You grep through a list of your body parts,
shooting the bits that look like feet. On the first try,
you don't shoot anything, and realize that you're matching
hashrefs instead of scalars. On the second try, you shoot
off your big toe instead of the whole foot (shouldn't have
used greedy matching in the regex). Finally, you shoot
yourself in the foot, generalize your code to allow it to
shoot anyone anywhere, and post it on CPAN as
SUICIDE::LITE.

Alternately, you post to Perl Monks asking the regulars
to write a finite automaton for you, and get your foot
blown off by tilly for your trouble.
